City Population Calculations

[Totally Hatebi]

I believe the population calculations on the wiki is old as I followed them and got the wrong results. Does anyone know the new ones?

How far off are you? Could be a rounding error. What is the exact formula you are using and could you give an example where you get the wrong answer?

I have been having problems with this too. I tried for example running the crime calculations %((103-Commerce)^2+Infrastructure*100/111111)-Police Stations*2,5 and then put real city data to test:

71,89 infrastructure, 79 commerce and 0 stations and ended up with 5,760647010647010647 or 5,76% rounded up, whereas the actual rate shown in the city stats was a mere 0,07%

This part of your formula is incorrect and that is why you are getting the wrong answer. It should be ((103 - Commerce)^2 + (Infrastructure * 100)) / 111111

Im running into problems with the population formula as well (Population = (Base Population - ((Disease Rate * 100 * Infra)/100) - MAX((Crime Rate / 10) * (100*Infra) - 25, 0) * (1 + ln(CityAgeInDays)/15)) and where base population = 100*infrastructure).
Im trying to apply it in google spreadsheet as follows: =(K41-((K40*100*F31)/100)-MAX((F35/10)*(100*F31)-25;0)*(1+LN(F36)/15))
I have checked and compared all the inputs with the actual numbers politics and war shows, and am thus 99.99% sure they are right. I end up with a population of 316.742, while it should be 449.954. 

In the translation the , in the original formula has become ; in mine. 

I can't find any other population formula, so this is what I'm working with. But I have completely forgotten where I got this formula and can't find it anymore either.

I got it. It should be Population = (Base Population - ((Disease Rate * 100 * Infra)/100) - MAX((Crime Rate / 10) * (100*Infra) - 25, 0)) * (1 + ln(CityAgeInDays)/15). Just a dumb bracket mistake. And the disease rate part should also be capped at 0 or above like the crime rate. Which would give:

Population = (Base Population - MAX((Disease Rate * 100 * Infra)/100, 0) - MAX((Crime Rate / 10) * (100*Infra) - 25, 0)) * (1 + ln(CityAgeInDays)/15)
